These are roots. But it's good that new ones are growing :)
New roots and new leaves every year are a must for it to bloom. If it does all that and still no flowers - put it in brighter spot, but not direct sunlight and give some fertilizer once a month. It should boost it.
What colour is it?
White'ish... with a hint of pale green.
I don't think I have a brighter spot in the house besides where it is now. It is brighter than the window it was in the first year I had it. That may be why all the roots. Just guessing.
Pretty :)
Let her grow then. She needs healthy roots and leaves to bloom.
